The legacy of the
Flash
began with Jay Garrick, a university science student, who as the result of a chemical accident gained access to the
Speed Force.
Although Garrick and his wife were childless, his heroism would inspire others to carry on his legacy.

When police chemist Barry Allen gained supersonic powers from a bolt of lightening which struck him in his lab,
he adopted the mantle of his childhood hero becoming the
Flash.

Allen's nephew Wally West would coincidentally also become subject to a similar accident which would allow him to become
his uncle's sidekick and eventually inherit his mentor's name and mantle as the
Flash.

Into the future numerous heroes either related to Allen and West or inspired by the legend spawned by Garrick will adopt
the name Flash, creating a dynasty of heroes which will exist for thousands of years.
